Sustainability

Thinking generations ahead

The D11T/D11T CD offer a number of sustainable benefits:

Fuel saving features like Enhanced Auto Shift help decrease overall fuel consumption. Decreases in fuel consumption result in a decrease in combustion of carbon, reducing greenhouse gases.

We are making our track-type tractors as quiet as possible so they have less impact on the communities where they operate. The new D11T offers an optional sound suppression package that delivers a 6 dB(A) (ISO 6395) reduction in the average spectator sound power level and a 4 dB(A) (ISO 6396) reduction in the average operator sound pressure level.

Ecology drains allow fluids to be easily captured for recycling or proper disposal.

Major components of Cat Track-Type Tractors are designed to be rebuilt. The Cat Certified Rebuild program conserves energy and materials by delivering a cost effective second, and even third, life for our machines.
